Here is a useful example. You can use Sconfig to install Windows PowerShell by following these simple steps:
1. At the command prompt, type sconfig.
2. At the menu prompt, enter 4, and then enter 2.
3. When the installation process is complete, you are prompted to restart the computer. Click Yes.

Once you’ve installed Windows PowerShell, you can access the PowerShell prompt by entering powershell at the command prompt. However, rather than running PowerShell within a command prompt, you might want to open a separate PowerShell window. To do this, press Ctrl+Shift+Esc to display Task Manager. Then in Task Manager, click New Task on the File menu. Type powershell in the Open field, and then click OK.
